SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 340,798, dated April 27, 1886.

Application filed January 27, 1886. Serial No. 159.921. (No model.)

To all whom t 71mg/ concern:

Be it known that I, FRANK B. MALLOEY, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sliutter-Vorkers; and I do vhereby declare the following to be a l'ull, clear,

and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In the accompanying drawings, Figure `l is a perspective view of a portion of a windowframe and one shutter with my improvement. Fig. 2 is a vertical section through the wall of a building, and showing myimprovement applied. Fig. 3 is a vertical section through the worm and its shaft, also showing in elevation the wornrwlieel', its journals, and the housing box of myinvention. Figs. 4 are perspective views of the two parts ol' the worm and worm- Wheel inclosing housing. Fig. 5 isa horizontal section in the line meot" Fig. 3. Fig. G isa detail view ofthe guidcway of the lever-arm made to travel therein in the act of opening or closing the shutter. Fig. 7 is a cross-section in the line 1/ g/ ol' Fig. 2, showing the twopart extension-shalt. Fig. 8 is a detail view of the detent for holding the shutter either open or closed. Fig. 9 is a modification of the construction of the tsvo-part extensionshaft,and illustrating the application of speedgearing thereto. Fig. l0 is a modification of the two-part extensiolrshalt, and Figs. 1l. are end views of said modilication; and Fig. l2 is a side view of a portion of the linished twopart extension-shalt, the shoulder on its inner end being formed by a metal ring seated in a groove, same as in Fig. l0.

Myinvention has for its object to improve, simplity,a11dcheapen the construction of shutteravorkers, whereby the same can be more readily and quickly applied, thereby saving time as well as greatly reducing the cost ol" attaching shuttenoperating devices.

In Fig. .l of the drawings I have shown a shutter, A, hinged to its l'rame A', and with improved shutter-worker I3 applied to the frame about midway of its length, and so as to have its lever-arm a engage with the shutter at a point midway ot' its length, and to this end I secure a guideway, c,to the middle rail, a2, of the shutter, said guideway being cast with a llat plate, as a3, at one end, and

adapted to be screwed to the rail aas shown, and with its body portion having a groove, as b, throughout its length on its under side, wherein the bent-up end b of the lever-arm a travels during the act of opening and closing` the shutter.

Fig. 2 shows my improved shutter-worker in working position with the frame A', the same consisting ol` a main square shaft, c,hav ing its outer end formed or provided with a worm, c, upon its enlarged cylindrical portion c, which. at either end, is formed with shoulders, as c e, and with reduced cylindrical journals, as at o c, so that when in place in the housing-box I) (shown in said ligure) the journals e' e2 willhave support in the front and rear plate of said box D, as shown, the shoulders e serving to prevent longitudinal displacement of the worm-shaft c. This worm shalt at its inner end is made to enter a long square socket of a handle-shaft, d, provided with a handle, d, to revolve the same, the handleshaft heilig made to pass through and have a proper bearing in a plate, d", secured to the inside of the l'rame A, and supplied with a hinged detent, as d, (shown clearly in Fig. 8,) to engage in an opening or slot, d4, in the hub ofthe handle el', and thereby, when desired, prevent the shutter-worker from beside pieces of variant widths, and that to facilitate its application for use I provide said extensionshal't with a housing of peculiar construction, and which is at once simple, cheap, and exactly adapted to receive and hold in place the worm c' a nd its worm-gear w. (Shown in Fig.

'Ihe housing D, as clearly represented in Fig. 4, consists of two main parts, as F and F' in said tgure. As delineated in Fig. 4, the part F as a whole consists of onehomogeneous mass of metal cast with a back plate, g, a projecting weather-guard, g', which, however, :may be omitted as not indispensable, and two projecting journalbearings, g2g, while a circular per- IOO foration, as es, serves as an opening through which the shaft c may be inserted into position, as shown in Fig. 2, and therein have a bearing for its journal e. Fart F is also provided with elongated apertures, as t' t i2, into which, respectively, the riveting dowels or projectionsj jjz are made to enter when the parts F and F are brought into juxtaposition, as in Figs. 2 and 3, and together secured by riveting, as signified atj. Instead of these elongated. openings i i i?, round holes may be elnployed to receive one or more pintles in lieu of the riveting .proj ectionsj jj'i, said plate also having screw-holes, as shown, by which to secure it in place, as in Fig. 2.

The part F (shown in Fig. 4L) is made in boX form with five sides, mostly closed, as shown, and with spaces, as o o', through its top and bottom walls, to receive with exactness the journal-bearings g2 g3 when the parts F and F are secured in juxtaposition, as in Figs. 2 and 3, said spaces terminating, as shown, in journal-bearing half-seats t t in said top and bottom walls, to correspond withlike haliseats, t ZP', in the journal-bearings g2 g o1" part F, and so form a complete journal-bearing seat for the journals t3 t of the wornrgear w when said gear, with its lever-arm a, is in working position, as shown in Fig. 3, andin which position the ends of the worm-gear cylinder w respectively abut against the under surface ofthe j ournal-bearing g2 and the upper surface of the j ournal-bearing g3, and thus prevent displacement of the worm-gear when in working position, as shown in Figs. 2 and 3.

By thus constructing the two-part housing D my shutter-worker may be readily adjusted into working position, as indicated in Fig. 9, by first passing the shaft c through the back plate, g, with the shoulder e of the worm-cylinder ci abutting against the back plate, g, of the part F. This having been done, the wormgear w is then set with its journals!3 and t* into the halfjonrnalscats i f" of the part F, as shown in Fig. This done, the metal boxing F is now brought up against the metal part F, the journal-bearings g2 g oi.' the part F entering the spaces o o' of the part F and the projections j jj2 entering the apertures t' i il of said parts, while at the same time the journal cL of the worm c will pass through the opening e" of the part F', and so have a proper journal-support, and in which position the several parts are maintained in xed place by the riveting atj, as indicated in Fig. 2.

By applying the slnitter-\vorkcr above the sill G and midway of the shutter, A, to be worked, I not only so locate it as to be out of the way while manipulating curtains which may be at the window on the inside, but also out of reach of meddlesome persons, while at the same time, by having the power of the lever c act midway of the shutter to open and close it, the leverage-power is exerted upon the shutter at the center of resistance,

and thus the shutter is moved withoutliability of torsional strains upon the shutter and the parts during such act.

I have shown in Fio. 9 two spur gear wheels, H II, one being on the handle-shaft' d and theother on a pin of the handle d', and the whole supported in a metal bracket, H2. By this gearing the speed of the worm can be increased. I have also shown in same view the soeketed portion of the handle-shaft d, constructed in longitudinal halves and held togetherl by a tube, Hf. These halves are connected to a collared portion, Hj, of the handle-shaft d.

In Figs. I0, Il, and l2 I have shown the handle-shaft d with a shoulder, I, formed by inserting a wire ring into a groove of said shaft. I also have shown the shaft as cast of malleable iron and with a turned-np lip, I', which lip can be turned down, as shown in Fig. l1, after the handle-shaft has been cast, and by this means the shaft may be east without a core at its end I2.

I would state that when the weather-guard g is used it serves its ordinary purpose of a top guard against ice and snow, and also as a means for keeping the lever-arm a in position, and this would be its function ifthe shoulders w ur of the worm-wheel were left oft'.

I contemplate leaving out metal, so as to lighten the housing at such points as may be practicable, and still retain the necessary bearings and connections between the several parts, and therefore do not confine myself to a completely closed housing.

What I claim as my invention is 1. The combination of the lever-guideway c,attached to the outside of the shutter, leverarm a, having a vertical journaled portion which cntersthe housing and turns therein,

. and horizontal portion having a bent-up end which enters the groove of the lever-guideway and works freely therein, the wormwheel w, applied between the journals of the lever-arm, the worm-shaft and worm c', and the housing I), formed of the two parts F F united, substantially as and for the purpose described.

2. The combination of the part F of the housing I), provided with half bearing-seats t tL and with riveting-apertures, with the part F, having half bearing-seats t 't and riveting projections orpintles, substantially as and for the purpose described.

3. The combination, with the two part housing D and the lever-arm teef the weather'- guard g', applied to the part F of the housing and acting as a guard,aud also serving to keep the journaled end'of the lever-arm in position in the housing, substantially as described.

In testimony whereof I affix my signature in presence oi' two witnesses.
